t m n Parallel Lines and a Transversal

t m n Parallel Lines and a Transversal Line

Alternate Interior Angles If a transversal line passes through parallel lines the ALTERNATING INTERIOR ANGLES are CONGRUENT. Another pair of angles that could be described as Alternating Interior Angles. m t 65 115 Interior 65 n This pair would also be congruent. Plane H

Alternate Exterior Angles If a transversal line passes through parallel lines the ALTERNATING EXTERIOR ANGLES are CONGRUENT. Another pair of angles that could be described as Alternating Exterior Angles. t 115 Exterior 65 m n 65 This pair would also be congruent. 115 Exterior Plane H

Corresponding Angles If the transversal passes through parallel lines the CORRESPONDING ANGLES are CONGRUENT. There are 4 pairs of CORRESPONDING ANGLES. t 115 m 65 115 n 65 115 Plane H

Consecutive Interior Angles If the transversal passes through parallel lines the CONSECUTIVE INTERIOR ANGLES are SUPPLEMENTARY. Another pair of angles that could be described as Consecutive Interior Angles. m Interior t 65 115 + 115 = 180 65 n This pair would also be supplementary. Plane H

Consecutive Exterior Angles If the transversal passes through parallel lines the CONSECUTIVE EXTERIOR ANGLES are SUPPLEMENTARY. Another pair of angles that could be described as Consecutive Exterior Angles. t 115 Exterior 65 m + n 65 This pair would also be supplementary. = 180 115 Exterior Plane H
